Rawlplug just turning, how can I get a grip?
I've used the polyester resin that is used with studs for resin fixings
in this application. Clean hole (important), squirt a little into
hole and push in plug. Leave for a couple of hours and rock solid.
The Ubiquitous and Wonderful Car Body Filler (UWCBF) can be used for
this as well.
Hardly surprising since UWCBF is polyester resin
